Thailand and other countries in Southeast Asia, such as Malaysia, Indonesia and the Philippines, are in the middle of their tropical monsoon rainy season, which lasts from May or June until November.

Soaring temperatures reaching 35 degrees Celsius are often followed by powerful tropical storms with thunder, lightning, rain and flash floods which cause rivers to flow faster and become dangerous.

Many of the under-developed nations struggle to cope with the heavy rain due to chronic under-investment in infrastructure and high levels of corruption funnelling away public funds away from projects such as roads and drainage.
